Check the connections
Check to be sure all connections are made positive to positive (+ to +) and negative to
negative (– to –) (Figure 4). Make sure that no loose strands of wire touch across terminals.
Bridged wires can short circuit and damage the amplifier. Tighten any loose connections
before you plug in the receiver and turn it on.

Test the speakers
To make sure your speakers operate correctly:
1. Place the speakers less than 6 inches (15 cm) apart, facing each other.
2. Turn on your receiver. Set the receiver to MONO (monophonic), if that is an option on
your receiver.
3. Make sure that all special effects (such as surround sound) are turned off.
4. Set the balance control to normal (center position).
5. Play some deep bass passages of music through the speaker.
The sound should seem to come from a point between the two speakers. The bass should
be full and natural. If it is not, one of the connections may be reversed, causing the speakers
to play out of phase (refer to "Make the connections" on page 6).
To correct the problem, make sure all the wires are connected positive to positive (+ to +)
and negative to negative (– to –). Then repeat steps 1 through 5 above to re-test
the speakers.
